posing and distributing machinessucn as ,Linotypef machines of the general organization represented in: Letters Patent; of theU ited States No. 436,532 to 0.

The present improvementsiin part are directed to a machine, capable of beingequipped with matrix fonts comprisingninetyj. different characters suitable for the more usualcomposition or straightfmatter and with matrix fonts comprising only seventy-twocharacters, for head letter nd di a or e cs wells taux fonts comprising a; lesser number of characters likewise used for display work. In such machines, the ninety and the seventytwo character fonts are contained in superposed main magazines shiftable as a. unit to bring any selected one into operative position, anda co mmon keyboard employed forthe release-of matrices from the magazine inoperative position, Since thematrices oi the two difie rent klndsof fonts occupy differently, located magazine channels because: of the difference in thesizeor the characters, it is customary to employ difi erent intermediate connections for operating the escapements or the different magazines in order that corresponding characters maybe released by the same finger keys. l V Q H In accordance with the present invention; the

, intermediate connections just alluded to include a [single bank of escapement reeds, some of Which constitute 'a group for actuating the escapements of a magazine containing a ninety character font,

and some a group for actuating thelescapements of a magazine containin a seventy two character' fo'nt. "Theescapement reeds in turn are l a 1f141fo1ai s. ,This inventionqrelates to typographical comtrol mechanism" is provided set initially to accord with the magazine .arrangementdecided upon, and thereafter, so long asthe magazine arrangement remains unchanged, the proper group of escapement reeds is brought intense as any selected magazine is moved intooperative position and this without any further thought on the operator spart,

The shifting of the ,rockbarsiin theninstant case is also effected-pneumatically andis gover ed fro the same controlbox,yas is also a pneumatically operated keyboardlock which is renderedactive automatically prior to a magazine shifting operation and the adjustment, of the, rock bars and which is later rendered inactive automatically uponthe arrival of the selected magazine in operative position and after therock bars have been adjusted to-connectthegkeyboard with the appropriate group of escapement reedsfortthe newly selected magazine. l l Also in accordance withthe present invention, the escapement devices associatedvwith the auxiliary magazine are actuated by escapement reeds operated from a group of rock; bars located in endwise alignment with'a corresponding group of rock bars associated with the main magazines.

When it is desired to use an auxiliary magazine,

pneumatic devicesunder the control of a finger key atthefront of the machine operate to shift the group of main rockbars into endwise connection with the auxiliary rock barsfso that matrices ,can be released from the auxiliary magazine by the operation of l the appropriate finger keys of operated by. rockbars allocated permanently to and operated inturn by the finger keys, of the keyboard mechanism, and said bars are shiftable endwise into connection with one group of escapement reeds or the other according :tcthe ,font

The, selection of the proper group oi escapement reeds is carried out automatically as the magazines are shifted tobring diiierent selectedones into operative position. For this purpo e: conthe lkeyboard mechanism. A second finger key enables the main group of rock barswhich act in,

the release of matrices frcm theauxiliary magazine to be reconnected forthe release of matrices from the main magazine. The two key are appropriately' marked Main and Aux, signifymg respectively; main magazine and auxiliary magazine, and they will by their position indicate whether or not the auxiliary magazine is connected for use. ,One of the features of the present arrangement resides in the fact that the
